This is a very informative and up-to-date book which makes me read right to the end, without stopping. Each chapter prompts me to read the next one. It deals very in depth about the current geopolitical issues affecting our world today - the air, the sea, the space and technology. It also gives a good case study about Antartica. very few geopolitical books that I have read has made such a deep analysis on such immediate issues. Not too intimidating for the reader who has little geopolitical know-how because of its explanation of current concepts and definitions (in the first chapter) as well as a glossary of key terms used.
